Abstract

Wireless transmission is affected by fading and interference effects which can be combated with equalizer.The use
of MIMO system promises good improvement in terms of spectral efficency,link relaibility andSignal to Noise Ratio (SNR).
The effect of fading and interference always causes an issue for signal recovery in wireless communication. Equalization
compensates for Intersymbol Interference (ISI) created by multipath within time dispersive channels. This paper analyses the
performance of Zeroforcing and MMSE equalizer for MIMO wireless chaneels. The simulation results are obtained using
MatLab tool box version 7.0 at RF signal processing lab.The Bit Error Rate (BER) characteristics for the various transmitting
and receiveing antennna is simulated in matlab tool box and many advantages and disdvantagesof the system is descrbed.
The simulation results show that the equalizer based zero forcing receiver is good for noise free channel and is suc
